Parrhasia (Arcadia)
Parrhasia was a region in south Arcadia, Greece. Parrhasius, son of Lycaon gave it his name.
Today, the area corresponds to modern southwestern Arcadia, west of Megalopoli, and southeastern Elis. The nymph of Artemis named Callisto, whom the goddess Hera made into a bear and Zeus later made into the constellation Ursa Major, was said to come from Parrhasia.
